City had increased property tax by about 6.8% while freezing commercial property tax. Because this is an election year, the municipal government has decided to absorb the cost of such increase and will issue a rebate on residential property tax. You'll still need to pay your property tax bills up front, City will issue a check to you sometime later this year, similar to the privatization of energy market last winter.
You can call the city to find out how much you are entitled. My property tax increase was about $380 dollars and I'm entitled to about $192 dollars in rebate.
